Problems solved by technology

[0004] During the processing of the keyway, for the taper sleeve with a small taper hole size (aperture φ<230mm at the small head end of the taper sleeve), the right-angle milling head of the general machine tool cannot pass through the taper hole, resulting in the failure to process the keyway
At present, even if the taper hole and keyway that can be processed are mainly used for machining the right-angle milling head with a small size, the rigidity of the right-angle milling head is not enough, so it is often necessary to reserve more margin for repair by the fitter, the production efficiency is extremely low, and the labor intensity And for the taper sleeve with longer length, the taper hole is also longer, which makes repairing more difficult, making it difficult to guarantee the straightness of the keyway and the symmetry of the two sides of the keyway, and it is difficult to guarantee the qualified rate of the parts
[0005] With the mass production of products, the requirements for products are getting higher and higher, the current production method is no longer suitable, and it is difficult to guarantee the production progress and product quality

Embodiment

[0027] Example: see figure 1 , figure 2 , image 3 as well as Figure 4 , a taper sleeve positioning device for processing the inner keyway of the taper sleeve by a planer, comprising a horizontally arranged rectangular bottom plate 1, on which a first support platform 2 and a second support platform parallel to each other are fixed along the length direction of the bottom plate 1 3. The distance between the two support platforms is less than or equal to the length of the taper sleeve 11; during production, the bottom plate 1 and the two support bodies are made of metal plates and welded together; one side or both sides of the support platform and the bottom plate 1 Ribs are arranged between them, which can make the connection between the bottom plate 1 and the two support platforms more stable and have a stronger bearing capacity.

[0028] Both support platforms are of plate-like structure, and the upper part is in the form of a ring structure. There is an angle of α betw...

Abstract

The invention discloses a taper sleeve positioning device used for machining an internal key groove of a taper sleeve by utilizing a planer. The taper sleeve positioning device used for machining the internal key groove of the taper sleeve by utilizing the planer comprises a horizontally arranged rectangular base plate, wherein a first supporting table and a second supporting table in parallel are fixedly arranged on the base plate in the length direction of the base plate, the two supporting tables are both of a tabular structure, the upper portions of the two supporting tables are both of an annular structure, a first cushion block and a second cushion block are arranged inside the annular structure of the first supporting table and the annular structure of the second supporting table respectively, at least three compression devices are respectively arranged at the side, deviating from the second supporting table, of the first supporting table, three first adjusting bolts are arranged on the periphery of the annular structure of the first supporting table, three connecting plates are arranged on the periphery of the annular structure of the second supporting table, and a check plate is arranged at the periphery of the second cushion block and can prevent the second cushion block from penetrating through the annular structure of the second supporting table. By means of the taper sleeve positioning device used for machining the internal key groove of the taper sleeve by utilizing the planer, the key groove of the taper sleeve can be accurately machined through the planer, particularly the taper sleeve with the small-size taper hole can be directly machined, and therefore production efficiency is improved, and labor intensity is relieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a taper sleeve positioning device for processing the inner key groove of the taper sleeve with a planer. [0002] Background technique [0003] The taper sleeve is the tapered shaft sleeve, which is an important part of the product. It has a tapered hole and is connected with the main shaft through a transition fit. When connecting, the key and the keyway are usually used for positioning; the keyway is required to have good guidance, so that the two sides of the key are close to the keyway, and the key is not allowed to be seized or burned after disassembly. Therefore, the keyway is required to have good straightness, and both sides of the keyway are required to have a high degree of symmetry (<0.01 / 300mm). [0004] During the processing of the keyway, for the taper sleeve with a small taper hole size (aperture φ<230mm at the small end of the tap...
